Problems solved by technology

Its disadvantages are: 1) Water and electricity cannot be completely isolated, which is not safe; 2) A water storage tank is required, and if it is powered on for heat preservation, it will consume a lot of electric energy; if it is heated again when it is used, it will take a long time to wait; The reduction of the temperature of the outlet water is unstable, and the mixing valve needs to be adjusted continuously, which is inconvenient to use

Embodiment Construction

[0019] An electric water heater, as shown in Fig. 1, includes an electric heating film heater 4 connected in series with three sets of pipes that can perform infrared heating on the water flowing through its inner cavity. The electric heating film heater 4 is connected in series with the water flow path in a liquid seal One end of the water flow path is connected to the tap water pipe network, and the other end is connected to the sprinkler device. The water flow path is connected in series with a manual throttle valve 17, a water flow magnetizer 2 and a water flow sensor that can control the electric heating of the electric film heater 4 1. In order to improve the safety factor, the water flow sensor 1 is set to two, which are respectively located at the water inlet and the water outlet of the water flow path and are electrically connected in series with the output pin of the CPU6.

[0020] The electric heating film heater 4 includes three, the ends of which are connected in seri...

Abstract

The invention discloses an electric water heater that includes electric heating velum heating body. The heating velum heating bodies are connected to water flow channel. One end of it is connected to tapping pipe net and the other end is connected to spray device. Water flow sensor is connected to each water flow branch in series. Environment temperature detecting device, water intake temperature detecting device, water outlet temperature detecting device and power control device are connected to CPU. The invention realizes water-electric separation. So it is safe and has high heat efficiency.

Description

Technical field [0001] The invention relates to an electric water heater. Background technique [0002] Known electric water heaters generally place the heating wire heating body in the water storage tank, and set the heating temperature through a variable-range controller; when the actual temperature reaches the set temperature, the heating wire heating body is powered off; below the set temperature When the time, the electric heating wire heating body is electrically heated again. The disadvantages are: 1) Water and electricity cannot be completely isolated, which is unsafe; 2) A storage tank is needed. If it is powered on for heat preservation, it will consume a lot of electricity; if it is powered on for heating, it will take a long time to wait; 3) With hot water in the storage tank The water outlet temperature is unstable, and the mixing valve needs to be adjusted continuously, which is inconvenient to use. Summary of the invention [0003] The technical problem to be solv...
